After that, the movable chassis 400 is moved down by driving the slide member 6 (slide member 5), and the movable chassis 400 stops when the pin 400c is positioned at the bottom of the inclined hole 6c. Thereby, the movable chassis 400 is positioned at the height position shown in FIG. Thus, a series of operations until the disk inserted from the insertion slot is transported by the drive roller 101 of the disk transport mechanism 100 and stored in the tray 301 of the disk storage unit 300 is completed.

The operation of ejecting the disc carried on the tray 301 from the insertion opening is performed by the same process as the above-described operation of loading the disc, except that the drive roller 101 is driven to rotate in the disc ejection direction.

Next, the tray 301 of the disk storage unit 300
FIG. 16 shows the operation of reproducing the disc carried by the
This will be described with reference to FIGS. The following description will be made as an example in which a disc carried on the second tray from the bottom is selected and reproduced.

In the standby state shown in FIG. 16, when a command to reproduce the disk carried on the second tray 301 from below is received by the control means (not shown), the wedge member 4
The movable chassis 400 is moved to position the disc playback unit 200 and the disc playback unit 200 at a height corresponding to the second tray 301 from the bottom.

That is, the sliding member 6 (sliding member 5) is driven to raise the movable chassis 400 to a position where the pin 400c is positioned at the second step from the lowest step of the inclined hole 6c. As a result, the movable chassis 400 is moved as shown in FIG.
, The disc carried on the second tray 301 from the bottom is in a reproducible state.

Thereafter, in order to secure a space between the trays 301 where the disc reproducing unit 200 enters, as shown in FIG. 17, the wedge member 410 is rotated clockwise in the figure. The cam surface 401d of the wedge member 410 comes into contact with the projection 301f of the third tray from the bottom, and pushes up this to move the third to sixth trays from the bottom upward. At the same time, the projection 301f of the second tray 301 from the bottom rides on the cam surface 401e and
0c. Projection 3 of tray 301 at the bottom
01f contacts the cam surface 401e.

Thereafter, the wedge member 410 further rotates clockwise in the figure. Thereby, the third to sixth from the bottom
The fourth four trays are moved further upward than shown in FIG. Further, the projection 301f of the tray 301 at the lowest position is pushed down by the cam surface 401e and moves downward. As a result, the second tray 30 from the bottom
A space is formed around the disc 1 so that the disc reproducing unit 200 can enter. FIG. 21 shows this state. This space is formed wider than the space for loading and unloading the above-described disc. Also, the second tray 3 from the bottom
01 is held by the wedge member 410 with the projection 301f penetrating deeply into the slot 410c.

Thereafter, as shown in FIG. 21, the disk reproducing unit moving mechanism is driven, and the disk reproducing unit 200 retreated to the retracted position (shown in FIG. 7) is moved to the reproducing position (also shown in FIG. 9). The disc reproducing unit 200 is moved and positioned in the space. As shown, a clamper 202 and a turntable 201 of a disc reproducing unit 200 are provided.
Enters the space in a clamp released state (a state in which the clamper 202 and the turntable 201 are separated),
The space has a size corresponding to it.

When the disk reproducing unit 200 reaches the reproducing position in the space, the clamper 202 descends in conjunction with the operation of the disk reproducing unit moving mechanism, and the disk is clamped. Simultaneously with this operation, the wedge member 410 slightly rotates counterclockwise to lower the second tray 301 from below. Thus, the disc carried on the second tray 301 from the bottom is carried on the turntable 201, and the tray 301 and the disc are separated. This operation and the lowering operation of the clamper 202 are performed almost simultaneously, thereby clamping the disk. FIG. 22 shows this state. The reproduction of the disc is performed in the state shown in FIG.

By the counterclockwise rotation of the wedge member 410, the third to sixth trays from the bottom are moved to the positions shown in FIG.
It moves downward from the state of 1. Thereby, the space occupied by the six trays 301 in the z direction is smaller than when the disc reproducing unit 200 shown in FIG. 21 enters. By this operation, it is possible to secure the space required for floating support during disc playback,
The device can be made thinner by this reduction.

The thinning of this device will be described with reference to FIG. FIGS. 23A and 23B show the disk reproducing apparatus of the present invention from the side. FIG. 23A shows a state in which the disk reproducing unit 200 is at the retracted position, and FIG. (C) shows a state in which the disk is clamped and the disk is played back.

Reference numeral 501 denotes a floating mechanism, which supports the main chassis 1 in a resilient state within the housing 500 to be in a floating state. Reference numeral 502 denotes a floating lock mechanism that constitutes a floating operation unit. When the lock mechanism is released, the main chassis 1 is supported in a floating state. As shown in FIGS. 23 (a) to 23 (c), the lock mechanism 502 allows the floating support of the main chassis 1 to be performed only when the disk is clamped, and otherwise releases the floating support. Is controlled.

In the case of FIG.
The space occupied by 0 is maximum. If the disk is to be played back in this state, the housing 500 must be formed with a size larger than the maximum space. However, in the case of the present embodiment, even if the housing 500 has a size just corresponding to the maximum space of the disk storage unit 300, the space occupied by the disk storage unit 300 after the disk is clamped is compressed, so that the floating support The necessary space can be secured. In this way, since the housing 500 can be formed as small as possible, the size of the apparatus can be reduced.

The operation of selecting and reproducing a disk stored in the disk storage section 300 has been described above.
As described above, in order to select a disk to be reproduced, the disk reproducing unit 200 and the wedge member 410 forming the disk reproducing space are integrally moved in the arrangement direction of the tray 301, so that the entire disk storage unit 300 is moved and reproduced. The apparatus can be made thinner than a disk reproducing apparatus that selects a desired disk.

Further, the disk reproducing unit 200 and the wedge member 41
0 is supported by the movable chassis 400 and moves together, whereby the positioning of the wedge member 410 with respect to the tray 301 holding the reproduced disc and the disc reproducing unit 20 are performed.
Since the positioning of 0 can be performed relatively easily and accurately, it is possible to provide a disk reproducing apparatus with high operation reliability.

Although the embodiment of the present invention has been described above, the present invention is not limited to this embodiment.
Various applications can be applied without departing from the gist of the invention. For example, the pair of drive rollers 101 and the moving mechanism thereof can be applied to a single player that reproduces a disc inserted from an insertion slot, and the same effects as in the present embodiment can be obtained.
